THEODOR KRIEG, OF BRUNSVICK, GERMANY.

APPARATUS FOR TRANSMITTING POWER.

SPECIFICATION forming part of Letters Patent No. 470,201, dated March8,1892. Application filed August 21, 1891- $erial No. 403,315. (Nomodel.)

To all whom it may concern:

Be it known that I, THEODOR KRIEG, man ufacturer, of Br11nswick,Duchy ofBrunswick, German Empire, have invented new and useful Apparatus forTransmitting Power, of

ment of this gear or mechanism, and then I shall explain its mode ofoperation.

The gear or mechanism is shown in the accompanying drawings, in whichFigure 1 is a front View, and Fig. 2a verti cal section through thecenter of Fig. 1.

The driven pin-wheels B, which are separated bya pulley, receive motiontransmitted to them by means of belts from the fly-wheel of asteam-engine or of any other motor. These wheels B are firmly keyed upona shaft g, carried by the two suspended bearings h. The upper ends ofthe two bearings h are firmly screwed to the top of the engine-frame.The driving-wheels B gear by means of the steel pins 2', arranged upontheir peripheries, with the pins 2 of the disk or wheel A, which pins 2"are arranged on both sides or edges of the periphery of the said wheel,as shown. The solid disk or wheel A bears with its whole weight upon theperiphery of the large disk or wheel D at the contact-point C. The shaftto of the pulley A turns between the anti-friction rollers o, fixed tothe bearing-forks h, for the purpose of reducing friction, the saidbearingforks being firmly screwed upon a slide S, which is moved to andfro by means of the hand-wheel H and screw P in guides or rails G, fixedto the top M of the frame of the engine. Upon the axis P is mounted anadjustable collar p, limiting its forward motion, and a guiding-collarp",which abut against the bearing P" of the screw P. By moving the slideS forward or backward, Fig. 2, by means of the screw P, carried by P",Fig. 1, the horizontal and vertical positions of the shaft 10 of thepulley A are determined or can be altered, while the forks h being opendownwardly the contact-point C of the wheel A with the large wheel D canbe likewise determined by the to-and-fro motion of the said slide S. Thewheel D is firmly keyed upon the motor-shaft (I, carried by theplumber-block L. The to-and-fro motion of the slide S by means of theaxis P serves also to couple or uncouple the wheel A with or from thewheel B, according as the teeth or pins 2' and c" are in gear or not,the wheel Abeing consequently drawn back when it is required to uncoupleuntil the said teeth t' and 2" are disconnected.

The top M of the machine-frame is carried by the pillars T, which may,however, be dispensed with in practice, this top being replaced by thecover of the machine-frame, if desired.

Mode of operation: The gear or mechanism operates as follows: The pulleycbetween the two pin-wheels B is set in rotation by a belt Z, so thatthe pins 1." of these two wheels gear with the pins 2', arranged onbothsides of the heavy wheel A, and thus transmit a rotary motion to thelatter. The working of each pin 1 of the wheels B resembles the actionof a lever having its fulcrum situated in the center of the shaft g. Thepower transmited by this lever is applied on the outermost end of eachsingle lever or pin 7}. tively small amount of friction developed inthis pin-gearing which is necessary to set the solid wheel A in rotationcauses an economy of driving-power. As soon as the intermediate wheel Ais set in motion power will be transmitted to the wheel D, due to itsweight on the said wheel D, owing to its shaft being unsupported. If therelative position of the axis 20 and of the shaft din different verticalplanes is taken into consideration, while at the same'time the intensepressure, as Well as the immense friction between the pulley A and thewheel D, is also kept in view, it will be obvious that by this frictiona power-transmitting effect of great intensity will be obtained at thecontact-point O", and the heavier the pulley A the greater will be thiseffect. That I claim, and desire to secure by Letters Patent of theUnited-States, is

1. In a device for transmitting power, the combination, with the drivenwheel B and the wheel D, of the intermediate Wheel gearing positivelywith the driven wheel and fric- The comparationally with the wheel D,said intermediate wheel being adjustable into and out of mesh with thedriven wheel, substantially as described.

2. In a device for transmitting power, the combination of the drivenwheel B, having radial pins, the intermediate adjustable wheel havinglateral pins, means for adjusting said wheel into and out of engagementwith the driven wheel and the wheel D, said intermediate wheel restingfrictionally on the wheel D, substantially as described.

3. The combination, with the wheel D and the driven wheel B, havingradial pins, ofthe intermediate wheel A, having, lateral pins adapted toengage with the radial pins, the shaft of said intermediate wheel beingfree to move vertically in its bearing to permit said wheel to rest uponthe wheel D and the bearings of said intermediate wheel being adjustablelaterally to throw said wheel into and out of mesh with the drivenwheel, substantially as described.

4. The combination of the driven wheel having radial pins, the wheel D,the intermediate wheel resting frictionally upon the wheel D andprovided with lateral pins adapted to mesh with the radial pins of thedriven wheel, the shaft upon which said intermediate wheel is mounted,the bearings for said shaft provided with anti-friction rollers, theslide carrying said bearings, and the screw and hand-shaft for adjustingsaid slide to carry the intermediate wheel into and out of mesh with thedriven wheel, substantially as described.

In witness whereot'l have hereunto set my hand in presence of twowitnesses.
